Work is simply a transfer of energy. Calculate the kinetic energy for both speeds, then calculate the difference. The formula for kinetic energy is KE = (1/2)mv2. If the mass is in kilograms, and the velocity (or speed) is in meter/second, the energy is in Joule.

### What is the difference between a power sled and a speed sled?

There is a big difference between a power sled and a speed sled. The power speed sled is generally bigger, heavier, can accommodate more weight. It also has handles to assist in resistance training.

### What causes the speed of a sled to increase or decrease when going down a hill?

Either the friction or density of the snow.

### What benefit would I get from a speed sled?

Speed sleds are used to improve acceleration when running. The speed sled training improves the burst speed of your leg muscles.

### What exactly is a speed sled?

A speed sled is a sled that can be attached to several weights. The sled is then harnessed to a runner's body while he runs. It is intended to improve endurance and acceleration for professional runners. It is not used at all in luge or bobsledding.

### What does the tobggan do on Club Penguin?

On clubpenguin the toboggan does nothing really special but if you buy it then you can use it in a sled race. But to use it you must buy it, then you click on your penguin card and you click on the toboggan in your inventory and then you are holding it. then you enter a sled race and you can see you penguin riding a toboggan. NOTE: this does not increase or decrease your speed during a sled race.

### What can I use a power sled for?

With a power sled you can develop strength in many areas. Such as speed, endurance, strength and leg strength.

What type sled?

### What surfaces are good for a speed sled?

Any traditional track and field surface should be good for a speed sled.You just need to know that the heavier you make the sled the more likely you are to gain dangerous momentum.

### How do mushers train there dogs?

They run all year and slowly increase their distance and speed each time they run. ( they are still using a sled to pull the musher)

### What changes as a sled goes down a hill in a straight line?

The velocity may increase if the sledge is accelerating. The momentum will increase as it is related to the velocity. The kinetic energy will also increase.
